Wonderful TriggerReview by BT
Installed a drop in flat faced AR trigger assembly in my predator rifle. I couldn't believe the difference it made. The guys at CMC make an excellent product and provide outstanding customer service. I am planning to install another one of their triggers in an M4. Can't say enough positive things about my CMC experience. Thanks Guys! (Posted on 1/9/2018)
Single Stage TriggerReview by m2stumpy
I purchased this trigger as an upgrade to a malfunctioning trigger in my rifle. What can I say about this trigger, I absolutely love it, consistent break and no slack at all. Well worth the money. Any rifle that I can upgrade to this trigger will be done, just can't say enough good about it. If you are on the fence about getting an upgraded trigger, get off them fence and get this one. I was shooting tight groups prior to getting this, they just got a little tighter. (Posted on 8/3/2017)

Awesome customer serviceReview by Brian
I purchased this trigger from my local gun store and when I attempted installation the anti-walk pins that came with it were just a bit too long allowing them to shift back and forth. I called CMC and they immediately sent me a new set of pins which fit perfectly. Thanks again for the fast and courteous customer service.

The trigger itself is a no frills work horse. The flat face feels great and has a nice clean brake with zero take up. The reset on it has a tactIle and audible click. Very good trigger. I am definitely going to get another one for my next build. These are leaps and bounds better than mil-spec. Don't hesitate and get yourself one! (Posted on 12/29/2016)
Love this trigger... butReview by Windturbinefreak
Built my rife from the ground up. Decided I wanted the best from the best. In best state!

Went with the flat trigger. I've had it on my rife for a year now and love it. Very clean and crisp. Excellent trigger...

My one tiny complaint and it on me. I wish I got the curved trigger. I finally got around to putting a b.a.d lever on and I have clearance issues.

U guys are what America is all about.Putting GOD first and using the talent and honesty he has given you. GREAT TRIGGERS !! GOD BLESS YOU !!! (Posted on 10/13/2016)
Very light! Crisp, no creep at all! Review by Sig 516 patrol gen 2
I just got the cmc flat 3.5. Installed in my sig 516 patrol. It dropped right in and done. Fits very nicely. Perfection! ***** star (Posted on 10/4/2016)
Great triggerReview by Dan J
Easy to install. The slight wiggle in the lower goes away when the pins and screws are installed. Breaks clean and crisp. VERY crisp. Went with flat trigger to increase distance in grip to eliminate finger creep. Also, got this trigger in an unconventional way. New LGS in my area had the CMC rep there and I bought this trigger direct from him but through the gun stores inventory. One of the screws was missing. Called CMC and they are sending a new pin set no questions asked. Love the trigger and the customer support! (Posted on 8/30/2016)

Great trigger...Review by Rollofire
I have 2 of these flat triggers in my ar-15s and they break very clean at 3.5 lbs. Just got another ar-15 I will be ordering another, this time I'm going with the curved 4.5 trigger as I'm using this gun for classes. (Posted on 3/9/2016)
Great triggersReview by Rollofire
I have 2 of the flat 3.5lb triggers on my ar-15s and they are very easy to install,use and are crazy fast. I'm going to order 2 more for my other ar-15s very soon. I think for the money why would you get any other trigger. CMC is my go to trigger from now on... (Posted on 2/29/2016)
Great drop in triggers Review by Travisk0024
I have this trigger in 3 different guns and it's amazing, you don't know how much more fun it is to shoot a fun with a aftermarket trigger until you get the chance to do it! No take up, crisp break and very low reset. Only issue you will is how much ammo you use (Posted on 2/26/2016)
Simple Installation, and Quality Built.Review by GlockUSMC
I am in the process of building my dream AR-15 and I was looking for high quality trigger for my build. I was recommended CMC by local gun store Ready Gunner you specialize in AR-15 builds. Let me say that I am extremely satisfied with the installation of my trigger and the quality of the trigger. Know I going to go enjoy some trigger time thanks to the folks over at CMC.

Best Single Stage Trigger On The MarketReview by VVACCWT
Very simple drop in install. No pre or over travel at all. After approximately 3500 rounds, breaks at 2.75 pounds. Crystal Clean Break & Very Short Crisp Reset. Exceptional Competition Trigger @ Even More Exceptional Price!!! Hands down the best trigger IMHO!!! Have recommended and sold many @ THE SHARP SHOOTER & at NICHOLS GUNS in Corpus Christi, TX. Come See Me @ Nichols Guns and You Won't Be Dissapointed!!! We Are An Authorized CMC Dealer!!! BEST TRIGGER EVER!!!! (Posted on 2/17/2016)

Highly Impressed Review by Hammer
This is a awesome trigger for the money. Dropped the 3.5 in a Ruger SR762 and its like a whole new rifle now. Amazing pull and crisp break. (Posted on 12/7/2015)
Best trigger I've used.Review by BROWKEY
I've been building my own AR's for about two years now and every time someone new fires one of them they are amazed by the trigger. Being a Texas boy I am so proud of the products your producing. Keep up the good work. (Posted on 12/3/2015)
Outstanding Review by Petejoe43
Having been a bolt gun shooter for decades, I have extensive trigger time on multiple makes. I decided to go with a CMC trigger for an AR build, and am very glad I did. No play, short travel, great reset, and ease of install make this one of the finest triggers I've used. I only expect the trigger to get better with use. Thank you for making such an outstanding American product! I will be back for more....great job! (Posted on 12/2/2015)
